CRUCIAL tests on the braking system of a historic train could pave the way for a series of special evening excursions for steam enthusiasts this summer.

The first Welsh Highland Heritage Railway (WHHR) train ran on the challenging gradients of the narrow gauge Welsh Highland Railway (WHR) at the weekend.

The five-carriage train, double headed by vintage locos Gelert and Gertrude, ran from the WHHR station at Porthmadog to Nantmor to test the braking systems.

Officials from both railways are delighted the trial took place. The two bodies have been at loggerheads in recent years following a disagreement about using a section of WHR track to take WHHR passengers along the newly reopened WHR from Porthmadog to Caernarfon.

WHHR officials had been openly critical of the refusal of access but a change of leadership has led to a more conciliatory approach.

On Saturday evening the train left the WHHR tracks and headed for the foot of Nantmor Bank – the start of a continuous six-mile climb to the summit of the line at Rhyd Ddu which makes the stretch the toughest railway in the UK.

After satisfactory completion of brake tests from speeds of up to 20mph to measure stopping distances, Gelert proceeded alone through the Aberglaslyn Pass and tunnels to Beddgelert to take water, before returning to Hafod y Llyn to test braking performance down Nantmor Bank before rejoining Gertrude and the train for the run back to Porthmadog.

This is the first time a WHHR train has travelled beyond the site of Traeth Mawr Loop – the end of the section of the railway laid by WHHR volunteers as their contribution to the rebuilding of the whole 25 miles of the Welsh Highland. The location is marked by one of the “Tin Tunnel” bridges built for farm access.

WHHR Chairman Martyn Owen said: “This is an historic moment for both railways. At times it seemed that it would never happen, but the wait has definitely been worthwhile.”

Ffestiniog and WHR general manager Paul Lewin added: “We’re very pleased to be working with our colleagues at the WHHR. The new spirit of cooperation can only bring benefits to both our organisations and to tourism.”

Further tests are planned over coming months and evening return specials are planned between Porthmadog and Beddgelert. The next movement from WHR to WHHR track is likely to be the visit of historic de Winton vertical boiler locomotive Chaloner on its way from Caernarfon to Porthmadog in July.
